Abstract

A device for supplying one or more arrays (1, 2) of burners (3), in which each burner (3) comprises at least one fuel inlet line (302) and at least one comburent agent inlet line (301). The said lines (302, 301) of the burners (3) are connected upstream respectively to at least one fuel supply duct (13) and to at least one comburent agent supply duct (9), and means (10, 11, 13, 16) are provided for monitoring and controlling the flows of fuel and comburent agent in these supply ducts. These means are operationally connected to at least one central unit (17) for controlling the distribution of the said flows to the arrays (1, 2) of burners (3)A device for supplying one or more arrays (1, 2) of burners (3).

Claims (7)

1. Device for supplying fuel and comburent to one or more arrays (1, 2) of burners (3), in which each burner (3) comprises at least one fuel inlet line (302) and at least one comburent agent inlet line (301), characterized in that said lines (302, 301) of the burners (3) are connected upstream respectively to at least one fuel supply duct (13) and to at least one comburent agent supply duct (9), means (10, 11, 15, 16) for monitoring and controlling the flows of fuel and comburent agent being provided in these supply ducts, these means being operationally connected to at least one central unit (17) for controlling the distribution of the said flows to the arrays (1, 2) of burners (3).
2. A supply device according to Claim 1, characterized in that each of the said ducts (9, 13) comprises at least one device (10, 15) for measuring the flow of fuel and respectively the flow of comburent agent.
3. A supply device according to Claim 1, characterized in that each of the said supply ducts (9, 13) comprises at least one valve (11, 16) for controlling the flow of fuel and respectively the flow of comburent agent, the said devices for measuring the flow of fuel and of comburent agent (10, 15) being positioned upstream of the corresponding control valve (11, 16).
4. Supply device according to Claim 1, characterized in that the said central unit is a programmable logic control unit (17).
5. Supply device according to Claim 4, characterized in that the said programmable logic control unit (17) acquires at its input the data from the devices (15, 10) for measuring the flow (Qc) of fuel and the flow (Qa) of comburent agent, the data relating to the power (P) required by the arrays (1, 2) of burners and to the ratio (R) between fuel and comburent agent, and supplies at its output signals (Sc, Sa) for controlling the opening of the valves (16, 11) for controlling the fuel and comburent agent.
6. Supply device according to Claim 5, characterized in that the said ratio (R) between fuel and comburent agent is predetermined and fixed.
7. Supply device according to Claim 1, characterized in that the fuel and comburent agent inlet lines (302, 301) open at their upstream ends into at least two corresponding manifolds (5, 4) supplied, respectively, by the fuel and comburent agent supply ducts (13, 9).
